UAV Frequency Bands

From HFUnderground

Drone data link bands. Digital data link. Control station radio link. UHF line of sight for most applications. Some use of UHF/SHF bands as well as various license-free remote control RC R/C, short range device (SRD) or low power civilian frequency bands, often vaguely referred to as “ISM bands”, “Part 15 bands” or “UHF”. 900 MHz, 2.4 GHz and 5.8 GHz are extremely popular due to their relatively high power output capability and wide bandwidth for high definition broadband transmission back to the control station, mesh network operation, use of frequency hopping, etc.

Currently a massive work in progress.
